Imishinga

1. Urwego rwo gushushanya urwego rwumushinga ni Urwego A, kandi hakoreshwa ibirundo byo gucukura.

2. Icyuma gifata kumpera yikirundo nikirere cya dolomite yikirere ≤4≥, agaciro gasanzwe ko kurwanya iherezo ntikiri munsi ya 5000kPa, diameter yikirundo ni d = 800, naho igipimo cyacyo ni ≥ 0.5m.Cyangwa ≤3≥2 ibice byibumba ryubusa, agaciro gasanzwe kokurwanya amaherezo ntikarenza 1500kPa, diameter yikirundo d = 800, kandi uburebure bwikirundo ni ≥35m.

3.Ibikoresho:

. .

Ubutaka bwikibanza burashobora kwangirika gato kumiterere yibanze ya beto hamwe nibyuma byuma byubatswe, kandi kubaka bigomba kuba bikurikiza "Code for Anti-rus rushing of Building Building" GB50046-2008

Ingamba zijyanye no kurwanya ruswa zifatwa hakurikijwe ingingo zibishinzwe muri Cushion: C15;Ikirundo cy'ikirundo: C30;Igiti cyo hasi: C30;Ibisobanuro rusange byinkingi Imiterere irambuye.

(2) Ibyuma:

Icyiciro cya HPB300 (ikimenyetso: Φ), fy = 270MPa;Icyiciro cya HRB400 (ikimenyetso: Φ), fy = 360MPa;Icyiciro cya HRB500 (ikimenyetso: Φ), fy = 435MPa.

4. Ubunini bwurwego rurinda imbaraga zigihe kirekire zishimangira umubiri wikirundo ni 50mm, kandi imbaraga ndende zumubiri zigomba guhuzwa cyangwa gusudira.

Ibisobanuro byemewe (GB50204) 5.4.5 na 5.4.6 ibisabwa.Ubunini bwurwego rukingira buringaniye burambuye muri "Ikintu Cyibanze Cyibanze Kurinda Ububiko";ibisobanuro rusange byinkingi imiterere irambuye.

5. Kumenya ibirundo by'ifatizo:

(1) Ikizamini cy'imizigo:

a.Kugirango umenye vertical vertical compressive ubushobozi bwikirundo kimwe, ikizamini gihamye cyakoreshejwe.Agaciro gasanzwe gahagaritse ubushobozi bwo gutwara ikirundo kimwe ni 4000KN.

b.Mubihe bimwe (buri bwoko bwikirundo), umubare wubugenzuzi ntugomba kuba munsi ya 3, kandi ntugomba kuba munsi ya 1% yumubare wuzuye;iyo umubare rusange wubwubatsi bwa pile uri muri 50, ntibigomba kuba munsi ya 2.

c.Ibisabwa bijyanye n'ikizamini bigomba kubahiriza "Ibisobanuro bya tekiniki yo gupima inyubako ya fondasiyo JGJ 106-2014".
